Hydrophilics

hydroheader

Polyvel offers an exceptionally efficient hydrophilic moisture absorber for polypropylene nonwovens whose uniform, low dusting, pellet form provides for cleaner incorporation and processing than topically applied wetting agents.


Product: VW351
Industry: Fiber Manufacturing
Function: Hydrophilic masterbatch for PP nonwoven fiber

VW351: Hydrophilic Masterbatch

Polyvel’s VW351 hydrophilic melt additive masterbatch is an effective wetting agent for melt blown non-woven polypropylene fiber. VW351:

  • Increases melt blown non-woven polypropylene fiber wettability at 5%
  • Makes fiber instantly wettable off line at 6%

As the VW351 % in polypropylene fiber increases, the absorptive capacity of a non-woven polypropylene fiber can be increased >4 times that of a non-woven fiber without VW351.

* Absorptive capacity = number of times weight increased compared to original dry fabric weight (ASTM test method D1117-77)
